Arbalest user?
I'd go with light - medium gear, like putting a max of weight at around 20 (?) for the body armor so upkeep isnt going to high either. I know 12+ weight is already heavy gear but its still alright for a crossbower who's also alright for melee fights (putting 1h/2h wpf and PS/IF).
Imo heraldic mails are always nice looking when holding a crossbow.
